King Frederik has officially ascended to the throne in Denmark, with tens of thousands of people turning out for the occasion in Copenhagen overnight.
The Danish Prime Minister, Mette Fredriksen, proclaimed the new king from the balcony of the royal palace.
King Frederik was joined by his wife - and now Queen consort, Mary - soon after, along with his four children.
His succession follows the abdication of his mother, Queen Margrethe, who announced her decision to step down just two weeks ago.
The BBC's Daniela Ralph spoke to Charlotte Cook from Copenhagen.
